[PCR-1000] Trunk Tracking PCR-1000

[CrazyC]

Hi all...

This is just a heads up to let ya all know that I have a working =
TrunkTracking program
for the PCR-1000.  It uses the sound card to decode the control channel =
and has options
to display the Control Channel Info info like Trunker including a dump =
listing...

It currently supports the Motorola type formats except APCO-25(9600 =
baud)..
In San Diego, I've tested it on the older TypeII system and Astro =
(Apco-25 3600 baud)...
With the TypeII system I get a signal of S-3 to S-5 and get a recovery =
rate from 90% to 100%.
And with the RCS South system I get a signal of S-7+, I get a constant =
recovery rate at 100%...

I started out this project using the code from MDT Monitor which uses =
the sound card to decode
mdt traffic.  I added the basic code from Trunker to decode the Outbout =
Signaling Words.  In this
way I was getting a recovery rate about 50% to 70% which wasn't good =
enough...

I then added code from the public released code from 'Capture' by Rick =
Parrish, specifically the Pll
section from that and the Pll section from 'Trunker'...  After some =
tinkering I was getting a recovery rate
to %80, but still not good enough...

I then turned to my OLD decoding algorithms from my Atari 800 that I =
used to decode RTTY through the PIO
port...  And after some tweaking here and there and trying different =
sampling rates I finally acheived 100% with a good signal source :-)


So now,  I am in the finishing stages of adding the final touches to the =
GUI and program operation...

If there is something that you would like to see in the application, =
please let me know and I'll see what I can do...

I should be releasing it to the public in the next couple of weeks for =
trial and beta testing...

Regards,
Jay
